Prior to 1819, the island was known by several names, dating back as early as the 2nd century, when Ptolemy's maps identified a coastal port at the southernmost tip of the Malayan peninsula, called Sabana. However, historians generally attribute a 3rd-century Chinese traveller's record describing an island at the same location called Pu Luo Chung - a transliteration of Singapura's early Malay name Pulau Ujong, as the first recording of its existence. Subsequently, the island was controlled by different kingdoms in Southeast Asia including the Siamese, Javanese, and Sultanate of Malacca from the 14th century and the Sultanate of Johor from the 16th century.
